Zimbra 5.0.22 with lightning 1.0 b2

In Zimbra are tasks and appointment two different things in different folders.
Can they be both shown on same calendar in lihtning ?

I have synchronized lightning with Zimbra calendar and all works well except I don't see Zimbra's tasks in Lightning and when I add task in Lightning it doesn't show up in Zimbra tasks.
I solved this by adding another calendar whic sync with Zimbra's tasks, but this isn't practical solution.
